Abstract

目的探讨磁共振全身弥散加权成像(WB-DWI)在初诊多发性骨髓瘤(MM)患者诊断和监测中的应用价值。方法收集2012年9月至2016年1月收治的107例初诊MM患者的临床资料,分析其中治疗前行WB-DWI检查的60例患者的结果,探讨WB-DWI在MM诊断和监测中的作用。结果60例患者中有57例均发现程度不等的骨质破坏病灶,WB-DWI阳性检出率为95.0%(57/60)。MM相关的骨破坏多累及中轴骨,以肋骨、脊柱及骨盆骨多见,肋骨为最易受累部位,检出率为96.5%(55/57)。有13例患者初诊时CT检查未发现骨质破坏,但行WB-DWI检查发现相同部位有弥散受限病灶影。8例患者治疗前后均行WB-DWI检查,结果显示8例患者治疗前最大病灶的中位表观弥散系数(ADC)值为0.984×10−3mm2/s;治疗后为1.142×10−3mm2/s,治疗后最大病灶的中位ADC值较治疗前高,且均高于正常值[(0.516±0.180)×10−3mm2/s];诱导治疗后WB-DWI检查结果与临床疗效相符。结论WB-DWI在诊断和监测MM中起重要作用,其诊断敏感性优于CT;诱导治疗后的WB-DWI检查结果与患者的临床疗效有一定的相关性,可用于疾病监测。
